This provides something similar to what `RwLock>` is or what

`Atomic>` would be if it existed, optimized for read-mostly write-seldom

scenarios, with consistent performance characteristics.

Read [the documentation](https://docs.rs/arc-swap) before using.

## Rust version policy

The 1. version will build on any edition 2018 capable compiler. This does not

include:

* Tests. Tests build and run on recent compilers, mostly because of

  dependencies.

* Additional feature flags. Most feature flags are guaranteed to build since the

  version they are introduced. Experimental features are without any guarantees.

at your option.
